Two teenagers have been charged with the murder of 64-year-old Dallis Coleman after Indianapolis Metropolitan Police detectives pieced together a case using a confidential informant, financial records and surveillance video.

Coleman was found inside his home in the 5200 block of Daniel Drive, near 56th Street and I-465, around 1 a.m. Oct. 17. Police believe Coleman was shot and killed while he was on his hands and knees on the floor.

Coleman's house had been "ransacked," police said, "as if someone had been looking for something." There were no signs of a break-in, according to a probable cause affidavit filed in the case.

Court records say that just before 5 p.m. the prior day a neighbor's surveillance camera showed Coleman arriving home with two women. About 25 minutes later, the camera also caught the biggest clue for detectives: a Toyota Camry with a mismatched rear passenger door pulling up to Coleman's northeast-side house.

Detectives also subpoenaed Coleman's financial statements and traced the use of his debit card after his death to multiple locations, including a grocery store, shoe store and gas station. Police tied that Toyota to at least two of the stops.

On Oct. 23, an IMPD detective discovered the Toyota driving to a pawn shop. Police arrested a person who became a confidential informant.

The informant told police that Coleman died during a robbery, pointing to two men, 18-year-old D'Andrae Robinson and 17-year-old Christopher Taliefer, as the ones who robbed Coleman, according to court records.

Robinson and Taliefer left the home with the two unidentified women, the informant told police, and drove away in Coleman's 2014 Kia Soul.
